, STOP-COCK BOX.

SPECIFICATION forming part of Letters Patent No. 404,049, dated May 28, 1889.

Application filed February '7, 1889. Serial No. 298,965. (No model.)

To @ZZ wiz/0m t may concern:

Be it known that we, ALEXANDER ORMsBY and HENRY EBERHART, both citizens of the United States, residing in Buffalo, in the county of Eric and State of New York, have invented certain new and useful Improvements in Stop-Cock Boxes, of which the following is a specification.

Our invention relates to certain new and useful improvements in stop-cock boxes,which will be fully and clearly herein after described and claimed, reference bein ghad to the accompanying drawings, in which- Figure 1 is a side elevation of the inside box, looking in the direction of the arrow V, Fig. 5, the outer box being in section through line c d, Fig. 4, so as to show the interior construction. Fig. 2 is a side elevation of the inside box, looking in the direction of the arrow WV, Fig. 5, showing its position over a stop-cock pipe. Fig. 3 is a vertical section on line e f, Fig. 4, through the upper portion of the outside box and cover, cutting through all except the bolt for holding the cover on and a portion of the hinge-pin. Fig. 4 is a top view of the box complete, showing the cover turned around so as to get at the stopcock; and Fig. 5 is a horizontal section on line a b, Fig. 1, showing a top view of a portion of the box in place over a stop-cock pipe.

The object of our invention is to provide a suitable means for protecting the stop-cocks of gas and water pipes and giving free access to them when required, and whereby the outside box may be put over the inner box and adjusted to its proper position, and still have a sufficient vertical movement to rise and fall and accommodate itself to the action of the frost in cold climates without in any way disturbing the position of the inner or lower box, which covers and protects the stop-cock and pipe.

In said drawings, 1 represents the inside tubular-shaped box, having an oblong portion,

4 passes through the opening 3, so that it will span the different sizes of stop-cocks and will more effectually prevent the dirt from crowding in too closely on the stop-cock.

At the top of the inner box is a spiral rib, 6, of considerable incline, so as to leave a large space between the spirals, making one turn around the box, as shown, or more or less turns, if desired. The outer box, 7, is made in a hollow cylindrical form and provided with an inside spiral rib, 8, having a pitch substantially corresponding with the thread 6 on the inner box. These spiral threads 6 and 8 are made with considerable pitch or incline, so as to leave room enough for the outer box to rise and fall with the action of the frost-that is, the box may rise and fall a distan ce equal to the distance between the points 9 and 10, minus the thickness of the rib 6, (see Fig. 1,)-and the movement may be made more or less by changing the incline of the ribs 6 and 8 to meet the demands of different localities.

At the top the out-side box is provided with a cover, 1l, hinged to the box by means of an invisible hinge consisting of the perforated lug 12, (shown in Fig. 3 and by dotted lines in Fig. 4,) and a pin, 13, projecting downward from the cover and provided with a small pin, 14, near the bottom, which is putin after the pin is inserted in the lug, the object being to prevent it from being taken entirely off or lost.

In the center of the lid or cover is a depression or recess, l5, having a hole, 16, through it, and the outer edge is provided with a downward-projecting rim, 17, adapted to fit over the upward-projecting rim 18 on the inside of'the box 7. A screw-bolt, 19, passes down through the opening 16 in the cover and screws into a long narrow holding-bar, 20, (shown in Figs. 1 and 3, also by dotted lines in Fig. 4,) and is provided with a pin, 2l, to prevent it from being drawn entirely out and to tighten it against the holding-bar 20 when required, as will be more clearly hereinafter Shown.

In the top rim, 18, of the box are two openings, 22, (shown in Fig. 4,) directly opposite each other, made sufficiently wide to allow the holding-bar 2O to pass easily in or o ut, so that when it is in, as shown in Fig. 1, and turned around slightly its ends pass under the flange 23 until it strikes against the inwardly-projecting lug 24. (Shown in Fig. l and by dotted lines in Fig. 4.)

The boX is set in place and operated as follows: The inner box, 1, is rst let down over the stop-cool; and pipe, as shown in Figs. 2 and 5; the outer b ox, 7, is then put on and turned around on the spiral threads 6 and 8 until it is brought to the height desired, after which the earth is packed in around it. When it becomes necessary to get at the stop-cock, the screw-bolt 19 is loosened by turning it with a wrench in the direction of the arrow fr (see Fig. 4) until the pin 21 wedges and tightens against the under side of the holding-bar 20, when it turns with the bolt until stopped by the lug 25. The cover 11 can now be lifted up and turned to one side, as shown in Fig. 4. The bar 2O being moved by this operation exactly opposite the openings 22 allows it to be lifted up and turned back out of the way. By this means all that is necessary to do is to keep unscrewin g the bolt 19 until it is stopped by wedging the pin 21 against the holdingbar. The cover is then easily lifted up and turned out of the Way. When closing it again, the holdin g-bar drops through the opening 22, and as it is held to the screw 19 by being wedged against the pin 2l, the moment it is moved to tighten the cover down the said bar 2O turns with the screw in the direction of the arrow s, Fig. 4, until stopped by the lugV 24,When its ends are under the flange 23, and the turning of the bolt may then be continued until the lcover is rigidly secured in place.

We claim as our invention- 1. In a stop-cock boX, a cover pivoted thereto by an inside vertical hinge or screw-bolt passing through the cover and through a holdingbar and having a pin, 21, at the bottom, in combination with a flange, 23, having openings 22, and lugs 24 25 in the top of the box, for the purposes described.

2. The combination of a vertically-pivoted cover, 11, a depression, 15,in the cover, a bolt, 19, passing through a hole in the depression 15, a holding-bar, 20, through which the bolt 19 passes, a pin, 21, through the lower end of the bolt 19, and an inwardly-proj ecting Harige, 23, having openings 22, and lugs 24 25, for the purposes described.
